I think you might have dismissed #2 too quickly. Although triangle is the
basic meshing engine underneath, it does allow a number of options which
are important in an application like yours.
There are other "free" generators.
I have used resolute at

which also uses triangle as its basic engine.
Also easygrid comes to mind.
None of these give you a "perfect" grid, and you will need to find a routine
which will allow you to edit your mesh, renumber your nodes, etc. I'm using
SMS but the underlying engine is unknown to me - it does not
produce "better" grids than say BatTri, but I can at least edit the grid.
Hope this helps.
